Hellenic Calendar/Holy Days

2026

701st Olympiad

Year 2

The calendar commonly used by the modern Hellenic communities is the Athenian, aka the Attik Calendar, referring to the general region of ancient Greece where Athens resided. 

Each month's New Moon phase possesses a number of Holy Days, starting on the first Day of the New Moon, with each one being a specific time of sacrifice to certain Gods or a particular God, Spirit or Hero. They are as follows:

First Day (Noumenia, meaning New Moon) - All Gods and specifically the Household Gods, and Apollon Noumenios and Selene.

Second Day - Agathos Daimon.

Third Day- Athene.

Fourth Day- Aphrodite, Eros, Hermes and Herakles. Some Hellenists also include Zeus and Hera on this Day.

Sixth Day- Artemis.

Seventh Day - Apollon.

Eighth Day - Poseidon and Theseus.

Ninth Day - Helios, the Muses, and Rhea.

Last 3 Days - All Chthonic Gods.

Last Day - Hekate.

While some Hellenists or organizations may begin these observances on the first of each month, our temple begins them when the New Moon is visible in our Sky. During Holy Days, you can also include other Divinities, Spirits and/or Heroes who are relevant to the Gods in honor. For example, on the Holy Day of Artemis, you can also pour a libation to the Forest Nymphs and Atalante.

The Attik Calendar follows a 12 month period, and each month is specifically named for its purpose. The year on the Attik Calendar actually begins with Hekatombaion (July).

In ancient Greece, years were divided into what is called The Olympiad, which marked the 4 year period between each Olympic Games. The Olympics first began in 776 BCE, and each 4 year period after that began a new cycle. Modern Hellenists use The Olympiad, in part, to establish a global timeline. It allows us to track seasonal festivals and leap years where they are necessary. The Olympiad also allows us to have a unified practice in the world by stepping outside of modern calendars that do not accurately serve the times of ancient Greece.

A leap year occurs when the following happens: If the 12th month ends before the Summer Solstice. In that case, the Month of Poseideon will be celebrated twice, called Poseideon II. To find out when this happens, you must do the following: If the Dark Moon in June occurs in a year before June 21st, add the second Month of Poseideon that year. 

When this happens, the Month of Poseideon is celebrated a second time, but not by leaving out Gamelion in January. Gamelion can be started later because the Greek calendar is not as rigid as our modern system. After the first Month of Poseideon is finished, start the second one at the next New Moon for 30 Days. During this time, celebrate only the New Moon Holy Days. When the next New Moon rises, start Gamelion. The extended Poseideon acts in honor of Poseidon because it is dedicated to Him because you keep Him in mind and devotion.
